iPhone says iCloud storage is full but over 2GB available
For some time now my iPhone has been telling me that the iCloud storage was full and so photos were no longer being uploaded. I therefore spent some time deleting stuff and now have - according to OS X and iOS - 2.4GB available. However Photos is still telling me that no photos or videos are being uploaded. Logging in to iCloud and looking at the stored photos confirms that nothing has been uploaded for 5 weeks.
It looks to me as though a switch was tripped when I hit the buffers but it has not reset since I cleared some space out. Any ideas what I am supposed to do to get it working again?
Thanks.
iPhone 6s, iOS 9.2
